State-of-the-art gaskets is what Cometic has been doing since its inception in 1989. This comes from their dedication to constructing gaskets for the most demanding race circuits like AMA and NASCAR. Today's lightweight engines are producing more horsepower, higher cylinder pressure, clamp load and extreme temperatures. Cometic's commitment is to provide innovative, quality gaskets while maximizing your engine's power and performance.

Cometic meets the needs of each specific gasket by using materials to match. Even the basic top end gasket kit features different materials for each gasket. The head gasket is constructed from non-asbestos, flexible graphite that is laminated to a stainless steel core. The manifold and base gaskets are constructed from non-asbestos nitride rubber-bound fiber. Cometic also includes copper gaskets where needed.

Cometic designs and builds their gaskets in the U.S.A.

Kit was missing valve seals and oring for bottom of cylinder for an 02 400ex. I understand that the pic is a "stock" pic but they're both in the picture. Plus every other company's top end kit that ive used (moose tusk, no name, oem) includes both of these items! Personally won't buy again.

I have not had a failure due to the gaskets after using them for two seasons. I really like the way the base gasket is so easy to remove when changing top ends. No scraping required........it just comes right off.

Bad

I bought this for my 07 yz 450f and the rivets in the head gasket didn't line up hitting the head caused it to leak everywhere. Going with stock

gasket didn't line up. on the head gasket where the coolant hole should be, there is just an "up" indicator that blocks the whole entire port. and also not sure if this is the case with all coolants, but don't use bell ray moot-chill coolant with theses gaskets, it breaks down the black paint/coating and it gets all in your calling system.

A: Different gaskets will give a different SQUISH. Using the Manufactures Tools you can set the squish based on base gasket thickness. Husqvarna or KTM tools will work. Check your Service manual for Tool part numbers.
